Structure of Y-type socket wrench

Abstract

A T-type socket wrench having three hexagonal rods on three ends of a Y-shaped handle, and three double-head hexagon sockets of successive hexagonal holes mounted on the three hexagonal rods and stopped at respective first positions by respective first steel balls for turning hexagon head screws. Each double-head heaxgon socket is moved inwards on the respective hexagonal rod and stopped at a respective second position by a respective second steel ball permitting a hexagon bit of different size on the respective hexgonal rod to project out of the respective double-head hexagon socket for turning a socket head screw or the like.

What is claimed is: 
     
       1. A Y-type socket wrench comprising: a Y-shaped handle having three hexagonal rods of the same size on three ends thereof, said hexagonal rods having each a first steel ball and a second steel ball received in two spaced holes on an outside surface thereof and partly projected over the outside surface and a hexagon bit of different size on a top edge thereof for turning socket head screws;   three double-head sockets detachably mounted on said three polygonal rods, said double-head sockets opposite ends thereof and a hexagonal boring bore connected therebetween; and   wherein each double-head socket can be stopped on the respective hexagonal rod at a first position by the respective first steel ball for turning a hexagon head screw, or stopped on the respective hexagonal rod at a second position by the respective second steel ball permitting the respective hexagon bit to extend out of the respective double-head socket for turning a socket head screw.   
     
     
       2. The Y-type socket wrench according to claim 1, wherein the three hexagonal bits of said three hexagonal rods are of different sizes, the biggest hexagonal bit having an outer diameter smaller than the outer diameter of said hexagonal rods. 
     
     
       3. The Y-type socket wrench according to claim 1, wherein the hexagonal holes of said three double-head hexagon sockets are of different sizes, the smallest hexagonal hole having an inner diameter bigger than the outer diameter of said hexagonal rods.
